The bright green areas shown where the signal from this transmitter is strong, dark green areas are poorer signals. Those parts shown in yellow may have interference on the same frequency from other masts.

Peter Henderson: Perhaps they have not updated their system. UTV legally has the allocation for a slot on the Freeview HD multiplex, as it is the "Channel 3 licence holder" in the province.

Peter Henderson: If UTV were definitely not going to provide a Freeview HD service, I would have thought that Ofcom would have made the slot available for the other PSBs to bid for.

I think UTV should lose there channel 3 licence and handed to ITV and go on to another channel number they are a law on to them Selfs they should of Launched there HD channel on sky freesat and virgin at the same time and when dso happens here one or two days later I think UTV have damaged norther ireland ecconomy eg in hd tv sales and hd installs because they where to slow on hd technology and how fast it was taken of here they are bunch of trogs and need to come into 21st century before UTV dies and goes the way of the dodos

Conor: If Ofcom could take the licence away from UTV, it would have to re-advertise it to all-comers and not just "hand it over" to another.

Quite what the madness of making UTV exclusive to Virgin Media customers is about is anyone's guess.

Given the lack of Freeview HD services in the province until late this year, there's not much damage to HDTV sales as such, but it makes no sense at all for UTV HD not to be on Freesat (and Sky of course).

Conor I couldn't agree more with you, it's disgraceful we have to wait until October before DSO especially if you consider we're expected to pay a TV licence fee but we're not receiving the same services as other licence payers who've already switched to digital. I think a rebate is in order!

As for UTV they are a joke and I suspect they will eventually fold considering the ultra cheap local programming they're broadcasting these days.

John: No! as explained in this excerpt from a fuller and somewhat lengthier explanation, >> commercial operators decided that the cost of providing the equipment, installation and ongoing operation of services from the 1,000 smaller transmitters would cost more than any additional revenue they could get from the TV channels that rent their broadcast capacity, as the work would only expand the actual number of homes broadcast to by 9% <<

There are numerous PSB only relays similar to Perth dotted all over the UK, and with the aforementioned applying to them all.
